On Venus, the acceleration due to gravity is 8.87 m/s2. How far would a 15 g rock fall from rest in 2.5 seconds if the only force acting on it was the gravitational force due to Venus?

Question

$$s=ut+1/2at ^{2}$$ I used this and got 27.7m

anonymous · Answer

The s is seconds right?

anonymous · Answer

I mean t

anonymous · Answer

No s is distance (displacement), t is time so seconds

anonymous · Answer

What does the s and u stand for?

anonymous · Answer

Sorry. It's lagging really bad right now

anonymous · Answer

S is displacement, U is initial velocity, 
However I have a problem with my solution in that it doesn't use the mass, are there other follow up questions that need mass?

Alright. I got the same answer. Thanks!!
